TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALBERT A. ROSE, of Binghamton, in the county ofBroomc, in the State of New York, have invented a new and usefulImprovement on Chums; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of this specification, inwhich-- Figure 1 is a perspective view.-

Figure 2 is a view showing the top and head block of the frame.

Similar letters of reference indicate corresponding parts in eachfigure.

The object of this invention is to provide a more convenient andexpeditious mode of operating the pendulum or vibrating churn. Thenature of my improvement consists in applying treadles to the frame ofthe churn in such'a manner that the box will be caused to oscillate moreeffectively and with less inconvenience than by the ordinary mode ofoperating it by hand; also in providing a more expeditious mode ofinserting and removing the dasher from the churn.

The churn-box A is suspended upon arms or pins projecting from the topof its parallel sides, hearing on the cross-pins B B of the frame. Inthe head-block C, I make a slot, D, connecting with the hole for thehandle of the dasher, of sufiicient size to admit and remove said dasherwithout moving the churn. This dasher is secured in its position by thewedge E. I attach two treadles G G to the lower part of the frame F F,which connect near the top of the box by means of connecting-rods H H;the pins in the churn that these ends work on are placed the properdistance from the line of the axis of oscillation of said churn, to giveit the required motion.

I operate my improvement by alternately pressing down the treadles, thuscausing the churn to vibrate with more energy and power than by theordinary means. When it is necessary to remove the dasher from thependulum or vibrating churn, the churn has to be detached from theframe, and the dasher-handle drawn down through the head-block C. Theadvantage of the slot D and wedge E is that the dasher can be readilyremoved at any time without the inconvenience of detaching and removingthe churn. The advantage of the treadles is that the required motion canmore easily be given to the churn by means of the feet, thusfacilitating the rupture of the globules and separation of the butterfrom the milk.

What I desire to secure by Letters Patent, i.s-

The manner of operating the pendulum or vibrating churn with the feet bymeans of the treadles G G, and the mode of inserting, securing, andremoving the dasher from the churn, substantially as described, and forthe purpose set forth.

A. ROSE.
